[Omake] omake bug with multiple targets

[Aleksey Nogin]

Sam,

Which version of OMake is that?

I can not reproduce this problem using 0.9.8.5:

% cat OMakefile
generator:
    echo $'#!/bin/sh' > $@
    echo $'touch a b c' >> $@
    chmod 755 $@

a b c: generator
    ./generator

.DEFAULT: a b c
% rm -f a b c generator; omake --verbose -j3
*** omake: reading OMakefiles
*** omake: finished reading OMakefiles (0.01 sec)
- build . generator
+ Shell.echo('#!/bin/sh') > generator
- build . generator
+ Shell.echo('touch a b c') >> generator
- build . generator
+ Shell.chmod(755 generator)
- exit . generator, 0.00 sec, code 0
- build . c
+ ./generator
- exit . c, 0.01 sec, code 0
*** omake: done (0.09 sec, 0/0 scans, 2/4 rules, 4/41 digests)
% omake --version
OMake 0.9.8.5 (release 3):
        build [Tue Sep 4 14:42:18 2007]
        on dangle.hrl.com

Default library directory : /usr/lib/omake
